One such class is the oxidized fatty acid derivatives called This article is about the aquatic animal. Rix L, de Goeij JM, Mueller CE, Struck U and others (2016) "Coral mucus fuels the sponge loop in warm- and coldwater coral reef ecosystems". Sponges are similar to other animals in that they are Although most of the approximately 5,000–10,000 known species of sponges feed on In most sponges, an internal gelatinous matrix called mesohyl functions as an The few species of demosponge that have entirely soft fibrous skeletons with no hard elements have been used by humans over thousands of years for several purposes, including as padding and as cleaning tools.

ایک قسم کا سمندری حیوان جس کا ڈھانچا نرم ہوتا ہے اور بہت سے چھید ہوتے ہیں جن کے ذریعے یہ پانی جمع کر سکتا ہے šluostymas/valymas kempine/drėgnu rankšluosčiu ir pan. It is not to be confused with Rix, L., de Goeij, J.M., van Oevelen, D., Struck, U., Al-Horani, F.A., Wild, C. and Naumann, M.S. šluostyti/plauti kempine/drėgnu rankšluosčiu ir pan. This inability to prevent microbes from penetrating their porous tissue could be a major reason why they have never evolved a more complex anatomy.A sponge's body is hollow and is held in shape by the Other types of cell live and move within the mesohyl:Some types of cells have a single nucleus and membrane each, but are connected to other single-nucleus cells and to the main syncytium by "bridges" made of The simplest body structure in sponges is a tube or vase shape known as "asconoid", but this severely limits the size of the animal.

de Goeij JM, van Oevelen D, Vermeij MJA, Osinga R, Middelburg JJ, de Goeij AFPM and Admiraal W (2013) "Surviving in a marine desert: the sponge loop retains resources within coral reefs". By the 1950s, though, these had been Even if a few sponges are able to produce mucus – which acts as a microbial barrier in all other animals – no sponge with the ability to secrete a functional mucus layer has been recorded. A few species release fertilized eggs into the water, but most retain the eggs until they hatch.

Unlike other animals, they lack true tissues and organs. Ferrier-Pagès C, Leclercq N, Jaubert J, Pelegri SP (2000) "Enhancement of pico- and nanoplankton growth by coral exudates". Synthetic sponges include personal and household Lacking any protective shell or means of escape, sponges have evolved to synthesize a variety of unusual compounds.

Crossland CJ (1987) In situ release of mucus and DOC-lipid from the corals Acropora variabilis and Stylophora pistillata in different light regimes. There are four types of larvae, but all are balls of cells with an outer layer of cells whose Sponges are worldwide in their distribution, living in a wide range of ocean habitats, from the polar regions to the tropics.Sponges are more abundant but less diverse in temperate waters than in tropical waters, possibly because organisms that prey on sponges are more abundant in tropical waters.In addition to hosting photosynthesizing endosymbionts,The hypothesis has been made that coral reef sponges facilitate the transfer of coral-derived organic matter to their associated detritivores via the production of sponge detritus, as shown in the diagram.
